BRAKE-HEAD ADJUSTABLE MEANS.

lSpecification ofLetters Patent. Patented Fb. 25, 1919.

Application filed November 17, 1917. Serial No. 202,500.

To all trimm may concern:

-Be it known that I, ARMAND H. PEYCKE, aI citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, 'have invented certain new and useful Improvements in Brake-Head Adjustable Means, of which the following is al specification.

This invention relates to brake mechanism, and more particularly to a novel brake head and hanger arrangement.

One of the objects of the invention is to improve and 'simplify means whereby a brake head normally may be yieldably held in a given position.

Another object is to connect brake heads and hangers inl a novel manner to occupy a minimum amount of space.

Another object is to provide a novel combination of a brake headand hanger ar rangement to meet the various requirements for successfiti commercial operation.

Generally speaking, these and other ohjects are accomplished by providing in brake mechanism, the combination of a brake head, a hanger associated therewith, and means carried by the hanger and engaging a portion of said bra-ke head to yieldably hold 'the latter.

i Thel invention is illustrated on the accompanying sheets of drawings, in which- -respectiveiy, of still another modification;

and,

Figs. 11 and 12 are rear and side elevaytions,-respectively, of another modification of the invention. l v

The various novel features of the invention will be apparent from the following description and drawings, and will be-.partieularly pointed out inthe appended claims.

Referring first to Figs. 1 and 2 ofthe drawings, it will be notedv that I have .-provided a brake beam having atrunnion; 1 1

upon which is adjustably rotatably mountedj a brake head 12. Also pivotally mounted upon the trunnin 1l are the jaws 13 and 1.4 of a hanger 15, the jaw being .pivotally mounted upon the trunnion 11t onA opposite sides of the brake head. The upper-portion of the hanger 15 is provided with the usual eye 16, by means of which it maybe connected to any suitable portion ofthe truck.

" In order at all 'times to maintain 'the braking surface of the brake shoel in conceive trioity with the tire of the associatedwheel, and also to prevent uneven` wear of the brake shoe, it is necessary that .the-.brake head be adjustably mounted upon a-'sufitable support for movement with respectt-hereto. i'

At, the same time normally the brake" head must not `be permitted too free an adjustable movement. Preferably t-he brakediead should be yieldablj. held in adjusted position, or any other position which it may. as-

sume in accordance with working conditions. To this end I have provided vieldableaneans which is interposed between the .brakehead and associated hanger.

In Figs. 1 and 2 I have shown-"a-spring-l` plate 17. the lower end of which is secured to or wrapped around a pin IS'eXtending between depending taill portions 19. off the hanger 15. The intermediate portieri of the spring plate conforms to and is pressed into engagement with the brakejhead trunnion bearing 20, the upper end ofthe spring 'plate being free to slide a limited amount-upon the front surface of the hangerV llslight-ly above the jaw portion. This spring plate 17v embraces substantially half of the-brake beam trunnion bearing Q0 and in this way .vieldably or frictionally holds the brake head in any adjusted positionand lat the same time permits the brake head auto`` matically to adjust itself in accordance v'with working conditions.

The arrangement shown in Figs. 3 and 4-V difiers from that shown in Figs'. 1 and 2,- in that the hanger 21 extends between the side walls 2i). and 23 of the brake head 24 and the 10 by looping the spring plate 48 around Plate-25 has two legs 26a the lower portion of'each of which is connectedto the cross pin 27 'carried by the depending tail pprtion 28 o'f the hanger, the leg portions 26 substantially the same as shown in Figs. A1-

and 2. The operation in both cases is the same.

In Figs. 5 and 6 I have disclosed a hanger I including two parts 29 and 30 separable along a longitudinal center line, said parts respectively having inwardly extending trunnion bearings 3l and 32 for the rece tion of the brake beam trunnion. Pivotall) Atrunnion bearings 31 and 32 is the brake head 33. It will be noted in this case that thehangeris mounted upon the brake beam trunnion'aiid the brake head 33 is mounted upon the trunnion bearings of the hanger portions 29 and 30. In this case the spring plate 34 is arranged with respect to the rake head and hanger, as shown in Figs.

, 1 and 2.

The modification disclosed in Figs. 7 and 8 shows the opposite ends of the spring plate I35 both anchored to the hanger 36, the ends of said spring plate being looped around ins 37 and 38, respectively, carried at the i ower end and at an intermediate portion 'of' the hanger. The ins 37 and 38 extend between the jaw mem ers 39 and 40 of the hanger 36, and the brake head trunnion bearing is arranged intermediate the jaw members 39 and 40. In this arrangement the spring plate 41 is more positively held thanin the arrangement disclosed in `the preceding figures. Its function is tlf' same as heretofore explained. The arrangement disclosed in Figs. 9 and '.10 is similar to the one shown in Figs. 1 and 2. It will be noted, however, that the spring `plate .42 has its upper end looped around the cross pin 43 of the hanger 44, and the Y lower end ofthe spring plate is free to slide agjlimit'ed amount upon the depending tail portion 45 of the hanger, the intermediate portion 46,-of the spring plate pressing -,-against the head trunnion bearing 47 to yieldingly hold the brake head in adjusted position.

f' The arrangement disclosed in Figs. 11 and -12 diers from that disclosed in Figs. 9 and the brake head trunnion bearing 49 at the front of the trunnion bearing 49 instead of g. around the rear portion thereof. The operation otherwise is the same.

lIn all of these arrangements the brake head isyie'ldably held by a spring plate' means carried by said connected to said tail ortion and engaging' automatically` .and yieldably retained in adjusted position in accordance with ogy-:fating conditions.

It is apparent -that there may be various modifications of the invention herein. partieL ularly shown andgdescribed, and it is my intention to cover all such modification whichA do not depart from the spirit and scope of the invention as set forth in the following claims.' g..
